'WALLPAPER MACHINE.

Application led February 19, 1927. Serial No. 169,596.

My invention consists of an improvement in machines for trimming, pasting, cutting, and manipulating wall paper for application to walls, ceilings, etc.

It has in view to provide a simple and applicable machine, operable in connection with a suitable table, whereby commercial wall paper may be drawn off from the usual roll through pasting mechanism and between severing mechanism for separation of the usual marginal edges, in any desired length, ready for application to the surface to be covered.

The machine as a whole involves various features of detail construction, adjusting l5 mechanism, etc., as shall be more fully hereinafter described.

The mechanism as a whole comprises the pasting and slitting machine A, adapted to be mounted by a suitable supporting bracket at one end of the folding or manipulating and cutting table B. The latter forms the subject matter of a separate companion application filed Feb. 19, 1927, Serial No. 169,597.

It will be understood that, while the machine is designed for co-operation and mounting relation with such table, it is not necessarily connedthereto, but may be utilized in connection with any suitable support and any suitable adjacent table or surface.

The machine A, in its entirety, comprises a unit so constructed as to be partially taker apart and packed into compact shape for carrying within a suitable case by the user, as is also the table B, as described in said companion application.

The pasting machine is preferably constructed of sheet or plate metal portions, rollers, etc., of a suitable kind, as aluminum or an alloy thereof, or of any other suitable alloy metal, adapted to withstand the active action of water or the elements for consistent endurance under the conditions of use.

At each end I provide oppositely located end plates 2 2, provided with securing brackets '3 riveted or screwed to the end plates, for attachment to the supporting bottom or base 4, preferably removably mounted on brackets 5 extending outwardly from the framework of the table B.

Base 4, which may be a board of comparatively thin light wood, rests upon brackets 5, as in Figs. 4 and 5, such base being provided with removable clips 6 having slotted terminals 7 extending upwardly behind the heads of screws 8 for connection therewith. Base 4 is provided at each end with clearance openings 9 for downward movementtherethrough of the severed edges of the paper at both sides, as it is drawn through the machine.

Brackets 3 ofend plates 2 are secured by their flat bases 10 and thumb screws 11, ex-A cross bars 14 f rial, to .which they are nixedly screws, providing a rigid bracing support for themachine tending upwardly through transverse slots 12 in the brackets, providing for exact lateral adjustment and fixture of the machine 4A on the shelf 4.- Bracket 10 is also preferably lprovided with an outwardly extending handle` 13 by which the machine may be exactly shifted and secured with relation to clearancel openings 9. p y

A End plates 2 are provided with two main or wood or other suitable matesecured, as by ortion of the frame and secured to end extending flanges 2 0 Plates 2 by downwardlase 21 for the palper is the flat supporting strip, preferably made of suitable sheet orl plate metal of the kind described. Between I 4the outeredgeof such supporting platform 21 and roll. 19 is a freely rotatable paper supporting roll 22 carried by its terminal stem bearings 23 in downwardly inclined slots 24, asinFig.7..

Just beyond the inner edge of platform 21 is an additional vsupporting roller 25, of wood or other suitable material freely and rotatably mounted by terminal studs or screws 26 in the end plates 2 and with its periphery substantially on the same level as the upper surface of the platform. The first supporting roller 22, as shown, extends slightly above the platform surface, so that when the-paste reservoir is in position, as in Fig. 9, its end walls-and the packing inserts thereof will deflect the paper downwardly at a slight angle as shown, insuring leakage-proof contact. In advance of supporting roller 25 is an additional'supporting roller 27, freely rotatableby its central end projecting stem 28 in yslots 29'A of plate 2.

Terminal collars 30 are secured lon the outer ends of stem28 and secured thereto by set-screws 31, maintaining the roller 27 in exact alinement and preventing lateral move-- ment during its free rotation. :At each end roller 27 is providedwith an annular clearance slot 32 for reception of the edge slitting kni-fe ofthe cutter mechanism, hereinafter described, for the purpose of severing the blank edges of the paper roll from its main middle portion. e v p I' Frame members 14 are connected at their ends b similar cross members 33, providing a stabilizing base framing. and upon such framework is secured by screws 34a flanged lGIS lupwardly extending thin tapered clearance plate 35. Such clearance plate extends intoV moval ofrollers 27 and 36 slot 32 so as to clear it of any accumulated cuttings or other waste material, maintaining the slot open at all times.

Intervening between rollers 25 and 27 is a comparatively small' freely rotatable paper supporting roller 36 mounted by its terminal studs 37 in slots 38 ofthe main frame, slots 29 and 38 thus providing for easy redesired. l,

For the purpose of slitting the edge portions of the paper as it is drawn forwardly from roll 19,-1 provide a separable L' shaped cross bar 39, the vertical portion 40-of which extends `at each end slightly beyond the top, for insertion downwardly through Vertical receiving slots 41 at the upper rear portion of each end plate 2. Terminal L- shaped lugs 42 are bent outwardly from such strip member and engage the outer faces of the middle y the main plates 2, while the lower portion of the vertical member 40 also extends through said slots and is provided with transverse locking openings 43.

Rotatable locking Vdogs 44 are pivotally mounted, at 45, to the outer side of each end plate adjacent to the slotI mounting of bar 40, andare providedwith the extended manipulating lugs 46, lugs 47 for partially cvering slot 29 when the locking dogs are opened,

` and the locking horn 48. Said locking horn lies annularly around the pivoting center 45, and 1s adapted to be thrust through the locking slot 43 at each end of the slitter bar frame, as in Fig. 7. In such position the slitupwardly when Y lll() ting mechanism is firmly held in position for use.

Mounted on the inner side of the L-shaped bar 39-40, is a knife supporting bar 49, lying along the inner face of the main bar, having flanged supporting shoes 93, and capable of a limited range of longitudinal adjustment along bar 39-40.v For .such purpose the main ba'r is provided witha series of slots 50 through which extend the holding screws 51 of bar 49, and which are thus capable of belng ixedly adjusted andlocated in slots 50 by thumb screws .52.

Cutter bar 49. extends out at right angles at each end, forming a terminal knife securlng. plate 53. A supplemental angle shaped plate 54 extends at right angles to the inner face' of adjustable strip 49, and is secured against the innerA face of the knife support 53, forming a companion piece therefora Such plate 54 has' an inclined edge 55, against-'which bears the upper edge of a comparati ythin knife blade 57. A supplemen clamping plate 58 lies over.the' .1xiii er facel'if blade 57,=.,having a similar edge -56, and is clamped to the outer bracket'fi'* end of the adjustable inner bar 49, so that the bladesmay be accurately and fXedly located with their inwardly inclined cutting edges extending into'the clearance slots or grooves 32 of roller 27. By such construction and arrangement the blades effect a clean severing separation of the edge strips 6l from the main paper strip, as it is drawn through the machine. I

Extending outwardly beyond the last orv trimming roller 27, and 011 a general level therewith, is a horizontal supporting shelf 62, pivoted in the end plates 2, at 63, by its downwardly extending lugs 64, and adapted to be thrown upwardly on the pivots when not in use for packing, as indicated in dotted Platform 62 is slitted at each end, asat 65, the metal being turned downwardly, providing a downward sloping shelf 66, for delivery thereover of the slitted edge (il through openings 9 in shelf 4 to a waste-basket or the like. End brackets 67, secured to the inner i edges of end plates 2,`and a vertical supporting plate 68, brace and support the plates-62 when in horizontal position, as in Figs. 7 and 9. The main paper strip passes onwardly over'the latform from the pasting and slitting machoine, ontothe table B to any extent desired.

For the purposeof applying paste to the pasting side of the paper as it is drawn from the roll, the full width of the strip passes unth strip a with just derneath thepastingbox or reservoir b, which is mounted between the end plates immediately above the first supporting platform 2l and rollers 22 and. 25.

Such pasting box \is removably mounted between the end plates, and comprises a longitudinal rectangular sheet metal paste holder, having end plates 69 and `longitudinal front side walls 70 and similar rear side walls 71. As shown, these side walls extend downwardly and then inwardly by sloping intermediate sections 72*73, andthen flare out' wardly by terminal sections 7 4-75.

The end Walls 69 are provided with transverse sealing strips 76 of sponge rubber or other suitable material, held tightly against the end walls 69 by supplemental inner holdingplates 77 secured to the end walls, as in Fig. 11. -Sealing'strips 76 press downwardly alongl the outer edges of the paperfstrip a as if/ is drawn through the machine, effectually sealing--the interior paste containing space of the reservoir against endwise leakage.

The front outwardly fiaring wall 7 4 eXtends downwardly over roller 22 with just sufficient clearance for the incoming strip, so that paste leakage in the opposite direction is effectuall prevented. i

For the purpose of also sealing "the other si e of the paste holder, and also of wiping sufficient paste, avoiding any unnecessary surplus, I provide addislots 85 in the end tional sealing strips 78 and 79, also of sponge i thumb nuts 83, for such adjustment and positive holding, as will be readily understood.'

By means of the strips 78, 79, assisted by the end strips 76, I provide a supplementalchamber adjacent the' main paste holding chamber. Such chamber will always contain a limited surplus amount of paste, ensuring even pasting of the surface from the first strip to the last, thus providing just the right amount at all times without variation or waste. Such paste as may pass under the firstwiper 78 when the reservoir is full tends to insure coverage of the strip beyond the first wiperas the main supply lessens, with final wiping by wiper 79.

The end plates 69 of the paste holding bos or reservoir are provided with projecting headed studs 84 extending through L-shaped plates 2 for separable-placement. Locking holders 86 are pivoted at 87 to the end plates 2 at each opposite side havl ing slots 88 for engagement of studs 8 4, as in Fig. 7, and lifting flanges 89 for upward swinging, providing for removal of the paste box.

As thus constructed the paste boX is capable of holding any desired quantity of paste, as say up toene-half pf its depth, the paste being supplied to the pasting side of the strip as it is drawn through for the full length of the paper a of roller 19. When the strip has been drawn through almost to its end, the last portion is cut off in front of the paste box'by shears ora knife, and the rear and front free edges of such remnant are then folded upwardly around each opposite side wall of the paste box and clamped thereon, asin Fig. 3, with the edges of the paper turned downwardly over inside the top. v

' Forl the purpose o'f firmly holding the remnant sealing strip in such position so that the box may be removed, I utilize endmost clamps 90 having an inner block member 91 and outer clamping flanges 92, adapted to tightly hold the end portions of the strip at each side to the sides 70, 71.

A middle clamp for lifting the box is composed of two side members 94 hinged to-v gether at 95, having lower block portions 9.6 and outer clamping terminals 97 turned iuwardly at 98.

lSuch clamp may be freely opened by pressing downwardly on its mid/(lle for release, and when applied, as in Figs.V 3 and 5, will firmly hold the sealing paper against the sides of the bo'x as it 'is lifted upwardly.

By such means the entirepaste box and its contents may be lifted away without leakage and laid asideA temporarily, providing for placement of an additional new paper roll`` and the drawing of its end portionsufficient'- ly far toward the table B to insure operation, after the paste box is replaced.

Thereupon the strip a is drawn forwardly,

the unpasted portion is cut off, whereupon the ope-ration of drawing Vthe paper out, with application of side edges may be continued throughout any desired length of section, dependent on the work being done.

Table B is provided at its inner edge with a terminal cutting edge 99, across whiclrthe fao surplus unpasted portion of the paper may be cut and thrown away,.afterr having been Q vdrawn forwardly underneath 'the paste box 7 ment of the various working parts, insuring complete coverage of the surface with paste accurate slitting of the excess edges, and ample provision against leakage, with facility and ease of operation, greatly contributing to V.a maximum output, and continued use. l

While the machine is designed for use with standard width of paper roll, of say a final net width after removal of the edges of eighteen inches, it will be understood that it may, of course, be made in any suitable size as to width or other dimensions. Also that it may be changed or varied by the skilled mechanic in different features of detail construction,
